The aim of this study was to describe the types of diseases that affect the nervous system of cattle from the State of Mato Grosso do Sul, Brazil. A retrospective study from January 2008 to December 2012 was perfomed, based on reports of cattle autopsies autopsy carried out by the Laboratório de Anatomia Patológica (LAP), Faculdade de Medicina Veterinária e Zootecnia (FAMEZ), Universidade Federal de Mato Grosso do Sul (UFMS). The material came from cases attended and forwarded to LAP by practicing veterinarians autonomous and from the official veterinary service. From 1028 cases studied, 588 presented a history of neurological clinical signs, 341 (53.75%) of which were diagnosed as affected bytrue neurological disease, and 247 (46.25%) had inconclusive diagnosis. The clinical records were reviewed to determine epidemiology, clinical signs, and gross and histopathological features. The most frequent diseases were botulism (16.67%), rabies (15.92%), polioencephalomalacia (8.05%), and herpesviral meningoencephalitis (4.31%). Other conditions were diagnosed occasionally, and included non suppurative meningoencephalitis (2.62%), suppurative meningoencephalitis (1.50%), brain abscesses and osteomyelitis caused by spinal cord compression (1.31%), tetanus (1.12%), hypothermia (0.94%), cerebral babesiosis (0.75%), malignant catarrhal fever (0.37%), and cases suggestive of oxalate poisoning (0.19%). No cases with lesions that may suggest of bovine spongiform encephalopathy were observed. |
